Well, i was recently asked to look at the plumbing at a house my client was thinking of buying - just to give an overview, and although things looked generally ok, i noticed PTFE on the threads of the radiator valves compression joint with the pipe and I did point out that this indicated DIY or less than professional standard plumbing work, which might indicate other short cuts elsewhere in the house.

Wrap too much PTFE around an olive and it just won't compress. I've been to a few leaky fittings and have found some idiot has applied too much PTFE around the olive and I've been able to simply push the olive with my fingers! A flood waiting to happen.
The only thing I put around my olives are a little Boss Universal, or if its heating work then Boss White. I never apply any PTFE or jointing compound to the threads of my compression fittings, its just utterly pointless.

ive never needed any ptfe on compression joints in over 20 yrs actually doing a job i was trained for. maybe you might need ptfe on compression joints if your a keyboard warrior or a diy'er making a guess at how to do things. there are so many google kings offering advice nowadays who knows whats right.
I really find this amusing, that some on here believe they know better than the manufacturers, here is another link, Conex fittings, no mention of any PTFE http://www.ibpconex.co.uk/pdf/conex_compression_fitting.pdf I have been installing for 28 years, never used any PTFE on compression fittings and never had any problems with any compression joints.

We'd all agree that Too Much of anything is, umm, "too much"
The same applies to jointing compound, flux, hemp, or muscle when tightening.
wow!
No mention of any jointing paste either. Can't understand how the manufacturers make a living. None in your toolbox, then?
johnD whats your trade?
wow!
JohnD, knock yourself out, carry on bodging joints with PTFE if thats what you want, but don't advise others incorrectly.
Simple advice for those wishing to do it correctly is follow the manufacturers instructions.
I'm a bikini waxer by trade and DIYer now and again.

I've seen plenty of green or white scale or run marks on joints made by professionals, as well as wet leaks. You must have been very lucky never to see one..
PTFE on an olive prevents leaks. Why wouldn't I use it?

ptfe on compression joints does not stop leaks. putting joints together properly prevents leaks.
you got any decent tips on bikini waxing?

In over 30 years i wish i had never came across a bit of damaged pipe i had to get onto or a ****e olive in an awkward position or every reducing set on rad valves on existing 8mm have been absolutly perfect etc etc. Guess some people are just really lucky

precisely, bit of paste is all you need.
lucky
bleedin miraculous more like
but to be fair its usually after some hairy assed spanner monkey has had a go at it
Well how much is enough then?
You do not need to apply PTFE to the olive for compression fittings and imho it shouldn't be applied. A little smear of jointing compound like I advised is perfectly adequate and does the job!
